ppm problem

[GanjaplantaSTL]

So iduno if i have a nutrient lock or what
i usually go with 2 feedings, 1 watering
all of them girls are in 2 week of flowering
reading 800-930 ppm out
iduno why but one of them is at 2200ppm and the last time before this watering i also gave it water it ran off at 1300. lastly the ppm was increasing as i was giving it more water instead of decreasing. Strangely eveythings looking good even at 2200 ppm run off please any advice would be helpful thanks

When was the last time you flushed them?
A bit more info would be helpful
PPM/EC, medium, nutes used, ph, grow style, etc

yesterday was the last time i flushed them and i water every 2 days
growing in soil (promix)
ppm was reading between 800-950 on all of them except for one at 2400ppm
strangely even the one of 2400ppm is all green looking healthy
using advanced nutrients micro with
black crystal, ph up & about to do my first shot of big bud.
i usually feed 2 times with nutrients and 1 time water for the cycle every 2 days
i flushed them before flopping them into flowering and was giving half of what i usually give them(water). when i switched them the first week i was using bit of a & b. only other nutrient i use is overdrive for the last two weeks. thanks for the help resinryder
